    Fast drawing directly to the Bitmap using C++

    fast bitmap borland c++ Nice! I'd say you need to create a 24 bits bitmap, that way each R, G, B value can range from 0-255 and with the shown code you'll get a grayscale bar (Edit: do change the "255*x" statements in simply "x"). With the 16 bits pixel format you get a colorfull pattern...

    Fast drawing directly to the Bitmap using C++

    rgbtriple +builder What exactly do you want to do? Paint the values in your array as a 1-D graph? Do the points in the array contain, for example, sine values? Of does the array contain 2-D information? For example an image? From your description it looks like the first case, but I'm not...

    J & K type temperture sensor

    max6675 with microchip c Why don't you just read some of the replies above more carefully, and start thinking for youself. EDA board isn't a design bureau you know. Put some effort in it yourself, you may actually learn something that way.

    J & K type temperture sensor

    picmicro thermocouple I think Microchip has a very nice appnote about this subject. It's called "AN844 Simplified Thermocouple Interfaces & PICmicro MCUs". https://ww1.microchip.com/downloads/en/AppNotes/00844a.pdf electronic design also has a nice example: **broken link removed**

    Chips in LCD module ODM 16216

    oriole,lcd data sheet The KS0066 / KS0066U is software compatible to the industry standard HD44780 controller. So you have a very standard LC module. The only thing that is a little bit different is the fact that the backlight uses only one pin (hence 15 pins, instead of the more common 16)...

    Why I2C is faster than SPI?

    The fastest serial memory devices are SPI. ST for example has 50 MHz SPI interfaces on their serial flash memory. See https://www.st.com/stonline/books/ascii/docs/10027.htm.

    Examples of PDIUSBD12 applications

    xp driver for pdiusbd12 usb download I assume you mean the PC driver? The Windows 98 driver can be found in D12Massstorage_win98driver_12feb01.zip which is included in the big zip file. For other operating systems the driver is already built-in, so there is no need to install a custom driver.

    Examples of PDIUSBD12 applications

    firmware philips pdiusbd12 Yeah, the Philips site is a bit of a mess lately... :cry: But I think I have the files you are looking for. The attached file contains the following drivers and firmware for the D12 Smart Kit: D12Massstorage_FW_6apr01.zip D12Massstorage_win98driver_12feb01.zip...

    Examples of PDIUSBD12 applications

    philips evaluation kit pdiusbd11 firmware Philips moved the files, I guess because they want to control who downloads them. After getting an account, you can now find the firmware source on the USB download site. **broken link removed**

    What does this declaration in C mean?

    Re: Declaration in C char Key = KEYPAD_NO_NEW_DATA,z; You could also write: char Key = KEYPAD_NO_NEW_DATA; char z; The comma simply allows you to declare multiple variables of the same type. So char a; char b; char c; a=0; b=1; c=2; and char a, b, c; a=0; b=1; c=2; are the same.

    EPROM/PIC Sinewane generator help

    You may find this page about a DDS synthesizer usefull. **broken link removed** The basic idea is very simple, and may be a good starting point for implementation in a PIC.

    What's lead free version IC?

    The leads coming out of the IC package are generally coated with a tin/lead alloy, to improve solderability. Because from 1 July 2006 all electronic assembly in the EU must be done without lead holding materials, manufacturers are now using alloys without lead contents. This is called...

    Using ftdi chip programming with Borland C++ Builder

    ftd2xx.h builder I do not have experience with the PLX chips, but with similar chips from Philips (PDIUSBD*) and National Semiconductor (USBN*). You really can't compare them with the FTDI chips, because you need to implement the USB handling in software. The FTDI chips take care of this for...

    Using ftdi chip programming with Borland C++ Builder

    ftd2xx.lib It's good to hear that it's working now! Yes, I've written several applications and interface DLL's for these chips (the FT232BM to be exact). At my company we use them for programming and interface boards. There are some issues, but in general the D2XX drivers are quite stable...

    Using ftdi chip programming with Borland C++ Builder

    ft245bm builder c++ I don't exactly know what you mean... But I'd use the import library method, since that is assumed in most of the sample code. I basically means that you add the .lib file to your project/makefile, which in turn satisfies the linker when the FT_* functions are encountered...
